Hi all

Would you mind if we ask DRV8711EVM?

<Question1>
How much is the layer of EVM? 2 layer?

<Question2>
How much is the EVM's thickness of the copper foil?

-In case of 2 layer-
 The component side : 35um?
 The solder side : 35um?
-In case of 4 layer-
 The component side : 35um?
 Power side : 70um?
 Ground side : 70um?

    Hi,

    <Question1>

    How much is the layer of EVM? 2 layer?

    -> If you go to the DRV8711EVM webpage and click on the Design Files, within the zip file that will be downloaded you will find the PCB file. This board is a two layer board.

    <Question2>

    How much is the EVM's thickness of the copper foil?

    ->35.56um on each of the copper layers (top and bottom layers)

    -In case of 2 layer-
     The component side: 35um?

     The solder side: 35um?
